T0012 HOLDER.

.spplleatien tiled April 1%, 1922. Serial No. 554,878.

Be it known that I, TIMOTHY C. FOLEY, a citizen of the United States, residlng at Ilenovo, in the county of Clinton and btate of Pennsylvania, have invented new and useful Improvements in Tool Holders, of which the following is a specification.

This invention relates to tool holders for planers.

The object is to provide a device to be attached to planers for holding tools during the operation of planing a group or series of locomotive pedestal shoes, wedges or other parts used in connection with locomotive edestals, or in other situations where rapldlty and accuracy of work is desired. u

rlhe principal features of the invention are the provision of a suitable head for the reception of the various tools used in planing operations to afford facilities for the proper adjustment ofthe tools inde-pendently of each other with respect to the body of the tool holder; and to eliminate the resetting of the tool holder for different operations.

' The device is especially designed for use in conjunction with the improved planer chuck shown and described in a co-pending application, filed by me on September 16, 1920, Serial No. 410,659, which has matured into Patent No. 1,420,029, and of which the present application is a continuation in part.

In carrying out the invention, I provide a holder for planer tools which may be readily attached to the transversely adjustable planer head or heads movable crosswise of the bed of the machine, and carried forward during the planing process by the cross head of the same, to cause one or more of the cutting tools carried thereby to act on the interior or exterior of said series of properly alined parts held by the abovementioned chuck, one of the interiorly acting tools being adjustable up or down in the holder to act as desired on the inside of the walls of the wedges, andthe exteriorly acting tools being laterally adjustable in the holder for a like purpose. The exterior tools are carried by swinging arms mounted in the holder, said arms being rigidly held inv vertical position, as viewed from the side, during the advancing movement of the carriage or cross head, and which, when the retrograde movement begins, are swung forwardly and outwardly from the work, so as to free the tools therefrom during the entire return stroke or movement of the carriage.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, @o taken in connection with the accompanying drawings formi-ngl a part of this specification, it being understood that while the drawings show a practical form of the invention, the latter is not confined to strict @5 conformity with the showing thereof, but may be changed or modified, so long as such changes or modifications mark no material departure from the salie-nt features of the invention, as specifically pointed out in the 7o appended claims.

In the drawings, in which similar reference characters designate corresponding parts throughout the several figures:

In locomotive repair shops where it is necessary to reface or otherwise repair great quantities of locomotive pedestal shoes and wedge blocks of various forms, in order that will ' they may worlr smoothly and give satisfactory service, ityis necessary to operate on a plurality of the same simultaneously in order to expedite the work, for these parts must be returned to and replaced in operaf tive position promptly to avoid tying up a rior of such wedges, shoes or other parts,

or for the use of' only one of such tools, or for the single or independent use of interiorly acting tools. which may also be used simultaneously' with one or both of the eX- terior tools.

lith these objects in view, the invention consists in a tool holding block formed of a single steel casting, suitably formed and machined, to provide a vertically disposed, elongated body portion l having,somewhat below its central point, oppositely disposed horizontal outstanding arms 2, integrally connected therewith and carrying, at their outer ends, integral, depending channel members 3, which are directed inwardly,

' at an angle to the body portion Land are provided, in their front faces, with correspondingly inclined slots or channels 4 extending from top to bottom of said members 3 and located along the longitudinal axes of the same.

The body member l is provided, at its upper end, with opposed, outwardly extending arms 5, whose upper surfaces are flush with the top of the body member and said upper arms are provided with suitable apertures for the reception of lfastening bolts 6, while the lower arms'2 are likewise apertured for the reception of other fastening bolts 7, said bolts 6 and 7 being employed to secure the tool holder rigidly to the front face of the usual planer heads 8 which are mounted for adjustment, transversely of the machine, upon suitable screws 9 carried in the cross head l() of the planer. y

The body member 1 is provided, in its rear face, with a longitudinally disposed,

l vertical slot 11, extending from top to bottom thereof, the said body member being slightly' wider below the lower arms 2 than above the same, as clearly shown in Fig. 3 of the drawing, and the said slot 11 is extended forward in this widened portion of the body member, as indicated at 11a in Fig. 6, toprovide a seat for a tool 11b of any ofthe usual forms. To the rear of this extended, or deepened portion at the lower end merece of the slot 1l, a transversely disposed stii fening plate 13 is welded to the rear face of the lower end of the body member, loelow theA lower edge of vthe planer head. 8, said plate 13 being held against the rear edge of the tool l2'by means of the welding and bolts ld traversing suitable alined openings in the lower end or the body and the said plate. The inner ends of binding screws l5, which are threaded through the front wall of the body and enter the slot il, impinge against the front face et the tooi l2 and bind the same against the front face of the planer head 8, said tool being employed for the purpose of planing the bottoms ot1 shoes. There is sucient clearance between the tool lll and the tool l2, to allow adjustment of tool l2. The tool lib, which snugly ts the transverse slot lia, has suitable apertures for i the passage oit the bolts i4: which securely hold the saine in place.,

Located in each inclined slot or channel d is a rocking, tool-carrying arm 16, formed of hardened steel and adapted to snugly fit said slot without any lost motion, the said arm being pivoted at its upper end by means of a tapered pin l? traversing the outer wall of the slot on an incline through a suitable inclined aperture in the upper end "of the said arm, which is semi-circular at its upper end as at 18, to permit the saine to swing forwardly within said slot, the

said pin li' being, seated intoa suitable inl clined aperture i9 beyond the channei 4: and

communicating with a vertically* disposed bore 20 formed in the upper tace of the arm- 2, and into which 1S adapted to be driven a suitable tool for forcing the tapered and inclined pivotal in 17 vout of' its frictional engagement in its seat, when it is desired to change, repair or renew the arm 16 together with its tool-carrying means about to be described.

By reason of the inclined slots d, the tool carrying arms 16 are inclined inwardly from their upper to their lower ends, and the mounting of the said inclined arms on the inclined pins enables them to swing up and away `from the work on the return stroke of the planer.

The lower end of the arm 16 is provided with a rectangular head 2l having a transversely disposed passageway 22 for the reception of the shank of a horizontal disposed cutting tool 23 held in the desired lateral adjustment by means of suitable set screws 24 threaded through the front walls of the. heads 21 and bearing against the tool in an obvious manner. The headv is also provided with a `vertically disposed aperture 25 into which may also be iitted a set screw to bear against the lower edge of the tool 23. v l

4 By releasing the screws 15, the tool 12 may. be lowered and positioned to cut the lid memos i tance between the same being equal to the necessary distance between the said walls.

In like manner, the tools 23 may be adjusted to cut the desired amount from the exterior of the walls, etc., of the shoes 26 by releasing the screws 24, the finer adf justment of the same being accomplished by means of the machine screws 9 in the usual manner. l

When the cross head 10 of the planer is advancing in its operative movement, as indicated by the arrow in Fig. 2, the toolsV either singly or together, by reason of their contact with the work, are held firmly in the head of the arms 16 which find their seats in the bottom of the channels 4, and when the return movement of the cross head starts, the said arms 16 swing upwardly automatically about their pivots and, by reason of the angular position of the latter, said tools are forced to move laterally and away from the work and not come into actual contact with the same until the next forward movement. When it is desired to hold the arms 16 permanently out of the active position, a pin indicated in dotted lines at 28 may be inserted through an aperture 29 formed in the outer wall of the channel member 3, said pin being adapted to extend into the channel and beneath the arm, when the latter is raised, as indicated in dotted lines in Fig. 4, so that the said arm is supported in elevated position and the tool 23 is removed entirely from the work.

As indicated in Figures 8 and 9 the double-edged interiorly vworking tool 11J may be employed to operate at the same time with the swinging, exterior tools 23, the downward feed of said tools, necessary to act on a new surface, being accomplished through the usual, vertical feeding mechanism forming a part of the planer head 8 and not illustrated in the drawing.

From the foregoing it will be seen that a simple, cheaply manufactured tool holder has been provided which may be easily applied to an ordinary planer of suiiicient" capacity for the purpose of operating on a plurality of locomotive pedestal shoes or wedges simultaneously, and that the tools may be adjusted to act on Vbothexterior faces of the work at the same time, or one side at a time, and that the said exterior tools may be put out of action while a centrally disposed tool is employed for the purpose of planing the bottom of the work, or a double edged tool may be employed to plane .both

interior vertical faces of the shoe at the same time.
